简要总结
The study on dairy value chains that will be conducted in Northern Senegal tests whether a health-related product (micro-fortified yogurt) targeted to children can be provided through the logistics of an existing value chain, and whether in return this can be leveraged to enhance the reliability of producers supply within this value chain. This study is conducted with a local milk factory, a recently established social enterprise, striving to produce dairy products with the milk collected from several hundred semi-nomadic small-scale producers in northern Senegal. This study tests: (i) whether the logistic created to collect milk in a remote area can be leveraged to deliver fortified yogurts to infants within its suppliers households; (ii) whether such products effectively help improve the nutritional status (anemia) of these children; and (iii) whether these health services encourage suppliers (and in particular women) to increase their milk delivery to the milk factory.
详细描述
Overall Objective
The overall study objectives are to better understand how a value chain can be made to be nutrition sensitive and ultimately leveraged to improve child nutrition, and to understand how certain incentives and services can be offered to actors within the value chain to enhance contractual relationships that strengthen the value chain.
In rural areas of developing countries where health products and services are poorly available, well organized agricultural value chains may be used to enhance access to such products and services to smallholder farmers. Yet, value chains in such countries face important challenges when it comes to enforcing contractual relationships, unless incentive-compatible schemes can be designed. As elsewhere, it may however be that health-related services themselves can, under certain conditions, serve as an adequate incentive towards more sustainable contractual relationships in the value chain.
Specific Objectives This study will address 2 key objectives.
- To test whether an incentive in the form of a daily micronutrient-fortified yogurt for children can be used to increase milk supply during dry season and enhance contractual relationship between suppliers and agro-processors
- To test whether the dairy value chain can be used as an efficient and sustainable means to supply essential micronutrients to young children, improve the quality of their diet and reduce anemia among young children during the one year duration of the intervention.

结局指标
主要结局
Prevalence of anemia in children 24-59 months after receiving iron fortified yoghurt during a one year intervention
时间窗: one year
The main outcome is the prevalence of anemia (hemoglobin below 11g/dl). Hemoglobin is measured in all children aged 24-59 months (by Hemocue analyzer) after a one year intervention at endline, in January 2014.
次要结局
- Frequency of milk supply by pastoralist during one year intervention(one year)
